This USB Mini B icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,400 icons, all in the same style and quality.
The main shape is a rectangle that is longer than it is tall with five small rectangles connected to the inside of the top of the rectangle. On top of the rectangle is a shape that is three quarters of a rectangle with two diagonal lines that connect to the top of the main rectangle.
